Rough Roman Memes

Increasingly repugnant actions must have increasingly disproportionately beneficial results to balance them out, I would say. There's nothing that I would automatically disqualify from a utilitarian analysis, but the more repugnant the action, the less likely there's any real-world justification for a scenario where that's the lesser evil out of the choices presented.

But again, my argument is not an absolute assertion of "Roman conquest was good", and I initially rejected the argument entirely precisely because it is a different argument from the question of Roman rule entirely, my argument is that the conflict of Roman and British polities and the conquest that resulted does not have the very modern dynamics you are ascribing to it.
